2021 3500HD in bed 5thwheel plug...

THE YETI · June 1, 2021

I posted in what I later realized was an older thread and figured I might as well start my own. And sorry but I'm cutting and pasting on my phone so sorry if the txt size and style varies...

My question is will a CURT Manufacturing 56070 (basically the 7 foot plug and play connecter that you plug in to the factory bumper plug and run the harness up to the side of the bed and normally drill a hole and mount an in bed plug) work in conjunction with a Hopkins 40975 (basically from my research so far, the plug end that will mount in place of the plug at the back of my bed on my 2021 3500HD)

So basically what I'm asking is if I mount this hopkins part in the factory spot in the bed will the curt part plug in to it and I'll be good to go? I've already ordered the curt part as I've used it a couple times before. But I ordered it before I got my new truck and then saw it had this plug in the bed for what must be a factory install plug. I'll attach links to the parts I'm talking about strictly to save you research on what I'm talking about...

Thanks in advance for any help...

Well, since I haven't got an answer yet. I figured I would order it anyway. Looking at pics and some research of sorts I'm thinking they should work together. Whether I have to take something apart or not, we will see. I'll be the guinea pig and post back with results for anyone else that may run in to this question too.

Curt harness showed up so had that installed in 5 mins or less. Had a bedliner put in before I got the truck and they went right over the plug in the bed so the hardest part was getting the plug out. Took the tail light off and then had to end up cutting around it through the bedliner just to pop it out. At least they out it on thick. Now I know. Either way. Have the loom and end zip tied to the tie down point while I wait for the hopkins plug end. Should be here hopefully Tuesday or Wednesday. Should be able to just plug in the CURT piece and snap the Hopkins piece in place and be done if all works out the way I figure it should. I'll let ya's know soon as I get it...

Hopkins plug showed up, and just as I suspected. They work together just fine. The hopkins plug didn't fit the in bed factory location perfectly at first but a quick adjustment or bending of the one side of the 'clip' and it popped in to place. So best of both worlds without having to splice any wires and cause an extra splice for corrosion or issues by combing these two products. Haven't tested the plug to my trailer yet to make sure I didn't get a defective one. But I'm sure it'll be good to go.
